Overview
Pathogenesis
- Renal oncocytoma is thought to arise from the intercalated cells of collecting ducts of the kidney.
Gross Pathology
- The tumors are tan or mahogany brown, well circumscribed and contain a central scar. They may achieve a large size (up to 12 cm in diameter).
Microscopic Pathology
- An epithelial tumor composed of oncocytes, large eosinophilic cells having small, round, benign-appearing nuclei with large nucleoli with excessive amounts of mitochondria.
